Va., assignor to Libbey-Owens-Ford Glass Company, Toledo, Ohio, a corporation of Ohio Application February 20, 1936, Serial No. 64,823 8 Claims. (Cl. 214—130‘) The present invention relates to improvements in glass handling apparatus and more particu larly to apparatus for handling relatively large sheets or plates of glass. In the production of continuous sheet glass ac cording to certain well known processes, the con tinuous sheet or ribbon of glass, after being formed, is carried horizontally through an anneal ing leer and emerges therefrom onto a so-called 10 capping table upon which the said sheet or ribbon is cut transversely into sheet sections and upon which the opposite side edges of the individual sheet sections may also be trimmed off if desired. The aim of this invention is the provision of a 15 glass handling apparatus of relatively simple yet compact and durable construction for receiving the individual sheet sections horizontally from the capping table, moving said sections to an upright position, and transporting them to any desired location in the plant for further treatment or for packing. Other objects and advantages of the invention will become more apparent during the course of the following description when taken in connec 25 tion with the accompanying drawings. In the drawings wherein like numerals are em ployed to designate like parts throughout the same, Fig. 1 is a diagrammatic plan view of glass 130 handling apparatus constructed in accordance with the present invention and shown in position to receive the individual sheet sections from the capping table, Fig. 2 is a side elevation of the glass handling apparatus, , Fig. 3 is an end view thereof, Fig. 4 is a plan view of the apparatus, and Fig. 5 is a detail section taken substantially on line 5—5 of Fig. 4. With reference to the drawings and particu * 40 larly to Fig. 1, Ill designates the outlet end of a horizontal annealing leer of any conventional or preferred construction and II a continuous sheet or ribbon of glass emerging therefrom‘. 445 Positioned closely adjacent the outlet end of the leer, in a manner to receive the glass sheet therer from and carry it forwardly, is a moving cutting or capping table I2 which travels in the same di rection and at the same speed as the continuous R50 sheet II. This table may take a variety of differ ent forms but is here shown, by way of example, as comprising an endless belt I3 trained about spaced rollers or drums I4 and I5 which are ro tatably supported at their opposite ends by the 155 horizontal supporting members I6 and I1, one of said rollers or drums being positively driven in any preferred manner to move the endless belt in the proper direction and at the desired speed. As the continuous sheet or ribbon of glass II emerges from the leer I0 upon capping table I2, 5 it is adapted to be cut transversely into individual sheet sections of the desired length and for this purpose there may be provided the cutting mecha nism designated in its entirety by the numeral I8. This cutting mechanism may be of any conven- 10 tional or approved construction since the speci?c structural details thereof form no part of the present invention. The cutting mechanism may, however, be of the general type disclosed in the patent to J. L. Drake, 1,724,261, August 13, 1929, .15 and is adapted for movement with the sheet dur ing the transverse scoring thereof whereby to permit accurate cuts. ' The cutting mechanism I8 embodies generally a pair of carriages I9 and 20 arranged at oppo- 20 site sides of the endless capping table I2 and movable longitudinally thereof upon suitable tracks (not shown) but which are located beneath the upper horizontal flight of said table. Extend ing transversely across the table and connecting 25 the carriages I9 and 20 is a supporting cross member 2I upon which is slidably mounted a cutter carrier 22 carrying the cutter 23. The cut ter carrier 22 and cutter 23 are movable along the cross member 2| by an operating rod 24, and 30 upon drawing of the said cutter across and. in con tact with the continuous sheet II, it is adapted to effect the transverse scoring thereof as indicated at 25. The glass ribbon is then broken along the score line 25 in the well known manner to pro- '35 vide individual sheet sections, one of which is shown at 26. If desired, the opposite longitudinal side edges of the sheet can also be trimmed off upon the capping table I2. Positioned at the outer end of the capping table 40' . I2 to receive the glass sheet 26 therefrom and to transport it to any desired location in the plant is the improved handling apparatus provided by ‘the present invention and designated in its en tirety by the numeral 21. This handling appa- 45 ratus includes generally a movable or portable carriage or truck A. upon which is mounted a tilting frame or rack B which is adapted to re ceive the glass sheet 26 thereon while disposed in a horizontal position as indicated by the full 50 lines in Fig. 3, after which it is swimg to an up- 7 right position as shown by the broken lines and ,while in this position is moved to any desired location in the plant. The carriage A consists of a substantially rec- - 55 2 2,106,573 tangular supporting frame comprising the spaced horizontal end members 28 and 29 connected together at one end by the horizontal side mem ber 30 and adjacent their opposite ends by the horizontal side member 3|. Secured to the side member 3|, adjacent the opposite ends thereof, are uprights 32 and 33 which are connected to gether adjacent their upper ends by a horizontal connecting beam ‘34;. ?ecured to the side mem 10 ber 38, adjacent the opposite ends thereof, are uprights 35 and 36 and a plurality of intermedi ate uprights 31 are also secured to said mem-v ber between the ends thereof. -All of the up rights 35, 36 and 37 are connected together ad jacent their upper ends by a horizontal connect- _ ing beam 38. Extending between and secured to the uprights 20 32 and 33 and the horizontal connecting beam 38 are transverse cross pieces 39 and ‘40; and the carriage may be further strengthened by brace boards 4| and v42 secured at one end to the cross pieces 39 and 40 and at their opposite end to the horizontal connecting beam 34. The uprights 35, 36 and 31 project upwardly beyond the ‘cross pieces 39 and 40 and passing therethrough is a rod 43 upon which the tilt ing frame or rack B is carried. The carriage A is mounted upon wheels 44 arranged at the four corners thereof and carried by the end mem 30 bers "28 and 29 whereby the said carriage can bevfreely moved about to transport the glass to any desired point. v ' ~ The tilting frame B is substantially rectangu lar and comprises the side members 45 and 46 and the end ‘members ‘41 and 48. Extending be tween and carried by said side members 45 and ‘46 ‘are ‘a plurality of intermediate members 49 arranged parallel with the end members 41 and ‘48. The end members 'of the tilting frame B are arranged outwardly of the ends of carriage A and are pivotally mounted intermediate their ‘en's; upon the rod 43. The end members 41 and 41B ‘and also the in termediate members 49 of the tilting frame'are » provided with‘aplurality of freely rotatable'roll ers 7'59 carried ‘by brackets 5| having vertical depending stems 52 which are loosely received within the frame members so as to-‘permit bodily rotary ‘movement ‘of the ‘rollers about Vertical axes as well as permitting them to freely rotate ‘about horizontal axes. The tilting ‘frame Bis ‘normally maintained in ‘a horizontal position, as'shown‘by‘the ‘full lines ‘in Fig. 3,‘, to receive the glass sheet thereupon ‘from the ‘capping table, ‘and after the lsheet'is received thereon the fsaid'frame is tilted to move the "said ‘sheet to an upright position as ‘indi ‘cated by the broken lines._ When in this posi '60 tion, the glass sheet is supported on edge upon casing, the forward movement of the bolt being limited by a shoulder 62 formed thereon. When in extended locking position, as shown in Fig. 5, the bolt projects through an opening in the latch plate 63 and is received within a recess 64 in 5 block 65 carried by beam 34. The latch bolt 59 projects beyond the opposite end of the casing 60 and has pivoted thereto as at 66 an operating rod 61 which is provided at its forward end with a handle portion 68. When 10 the tilting frame B is moved to horizontal posi tion, it will be locked in such position by the latch bolt 59. However, when it is desired to swing the ‘frame to its upright position, it is simply necessary‘ forthe operator to grasp handle 68 and ‘pull rod 61‘ forwardly, thereby withdrawing 15 the latch bolt 59 from looking position where upon the ‘counterweights 54 will act to automati callyuswing the frame upon rod 43 to upright position. 20 The carriage A, if desired, can also be provided at ‘each end thereof, with a conventional type of door stop or check 69 for maintaining the car riage in proper position during the receiving of the glass sheet upon the tilting frame or its re 25 moval therefrom. Since these stops may be of any Well known type readily obtainable on the market, it is not considered necessaryto either illustrate or describe in detail the construction and operation thereof. 30 It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without ‘departing from the spirit of the invention or ‘the scope _of ‘the subjoined claims.
